Dr. Francine Langstrom

History

Francine Lee was the girlfriend of Dr. Kirk Langstrom, the scientist who invented the bat-gland serum and involuntarily transformed into the Man-Bat. Refusing to give up her love for Kirk, Francine took the serum herself and was transformed into a female Man-Bat, which affected her mind. The Batman gave them both an antidote, and the happy couple was married. Some time later, an atomic blast reactivated the bat-gland chemicals in her blood, after which she was

repeatedly transformed into a vampire bat, controlled by the evil Baron Tyme. Still later, Francine adopted the heroic identity of She-Bat while fighting the villainous Snafu. These days, Francine is cured, and dedicates her life to bring up her children, Aaron and Rebecca. She is currently working with Batman and his team of

Outsiders

as their lead scientist along with her husband Kirk as her assistant.

Francine is later seen with her children in Gotham, holding a device fitted with a timer. They appear to be suffering from the same delusions that Kirk was enduring as Man-Bat. The three of them then jump off a building but Batman and Robin grapple to rescue. The Dynamic Duo defuse the bomb and then interrogate Francine for information. They inform Francine about Kirk's delusions and she tells them about the device she was holding but suddenly the building that they were in, begins to glow with a white light. The Langstroms escape the building while the Dynamic Duo deals with the White Knight.
